手动更改另一个时，自动更改datagridview列的宽度 [英] Changing width of datagridview column automatically when changing another manually

问题描述

大家好，



我有两个 DataGridView 停靠在我的表单其中我将 AutoSizeMode 设置为填写我想自动更改第二个 DataGridView 列宽度与第一个列的 width 更改相同。



我试过这两种情况：

Hi all,

I have two DataGridView docked in my Form in which I am setting its AutoSizeMode to Fill I want to change automatically the second DataGridView column Width the same as the first one's column width change.

I tried these two cases:

private void dataGridView1_ColumnWidthChanged(object sender, DataGridViewColumnEventArgs e)
{
    dataGridView2.Columns[e.Column.Index].FillWeight = e.Column.FillWeight;
}

private void dataGridView1_ColumnWidthChanged(object sender, DataGridViewColumnEventArgs e)
{
    dataGridView2.Columns[e.Column.Index].Width = e.Column.Width;
}

在这两种情况下，加载包含这两个 DataGridView的表单时会出现此错误：



调整自动填充列时无法执行此操作。



请有人帮助我吗？



提前谢谢，

：）

In the two cases this error appear when loading the form that contains these two DataGridView :

This operation cannot be performed while an auto-filled column is being resized.

Please can anyone helps me ?

Thank you in advance,
:)

推荐答案

错误消息告诉您失败的原因。您将AutoSizeMode设置为Fill，因此无法手动设置宽度。



您需要更改 AutoSizeMode 要在手动设置大小的网格上 NotSet 或无。

The error message tells you why this fails. You have the AutoSizeMode set to Fill and cannot therefore set the width manually.

You will need to change the AutoSizeMode to either NotSet or None on the grid that you want to set the size manually on.

试试这段代码

try this code

foreach (DataGridViewColumn dcol in dataGridView1.Columns)
            {
                dcol.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
            }

dataGridView1.AutoResizeColumns();
dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;
